UNITED STATES PATENT OFFICE SAMUEL F. SEELY, OF TOLEDO, OHIO, ASSIGNOR OF TVVO-THIRDS TO JAMES W. SEELY AND WILLIAM M. SEELY, BOTH OF SAME PLACE.

SPRING FOR BEDS, 80C.

SPECIFICATION forming part of Letters Patent No. 276,901, dated May 1, 1883.

' Application filed October 31,1882. (NomodeL) To all whom it may concern Be it known that I, SAMUEL F. SEELY, a citizen of the United States, residing at T0- ledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Springs for Beds, Cots, Lounges, 8tc., of .Which the following is a specification.

The object of my invention is to produce a light, easy, and flexible bed-spring that may be easily and quickly trussed up or slackened, so as to be made suitable for a heavy or light person, so constructed that the two halves of the bed work independent of each other and never present a concave surface to lie upon.

My invention relates to that class of bedsprings in which there are longitudinal slats of wood, forming springs, whichareplaced opposite, above and below, thus forming an elliptie, the ends of which rest in loops formed on the ends of peculiarly-formed coiled or spiral springs, through the coils of which a rod is passed, to which a wire rope is attached, by means of which each section may be trussed up so as tosupport a greater or less weight. The sections are tied together by a transverse slat supported by coiled springs, upon which the wire truss-ropes rest. Upon the slats I have also mounted a head-elevation for invalids, the whole ofwhich may be attached or detached to or from a folding truss or support, thus forming it into a cot or single bed. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a perspective view in full; Fig. 2, a perspective view of the truss or support; and Figs. 3, 4., 5, details of parts.-

Similar letters refer to similar parts throughout the several views.

The longitudinal slats A A A, 850., tied together by the transverse bars I I, form the upper halves of the elliptics, and'the lower slats, B B B, 850., tied together by the transverse bars I l at the ends and Kin the center, form the lower halfof the elliptic. The springs (l O O at each end loop over the upper and lower halves of the elliptic sections, as seen in Figs. 3 and 4. Through the openings formed by the coils of the springs O U, 850., a trussrod, E, is passed at each end, and into each of these truss-rods E E is secured a longitudinal truss-rope, D, of wire or other suitable matevents the upper elliptic sections, A A. A, from pressing down below a straight line when weight is applied on them.

H is an invalid head-elevation attachment, supported at any angle by means of the props J J.

Fig. 2 represents a folding truss or support which attaches by means of hooks X X to the lower section of the elliptics B B, and thus converts it into a cot-bed. This truss or support consists of the legs M M, joint-plates S S, tie-rails N N, and the jointed pivoted braces P P. I v

The whole construction of the invention is plain, and the operation is simply the operating of the truss-rods E E, so as to adapt the two upper sections of the elliptic A A A, 850., to a. greater or less weight, as in the case of a large and small person one half of the bed would need to be much tighter than the other, the two halves of the bed working independent of each other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The double loop ended spring D (l, together with the truss-rods E E and the longitudinal truss-ropes D, by means of which the upper and lower sections,A A and B B,of the elliptic are held firmly in positiou,as described and specified.

2. The truss-rods E E, in connection with the springs O O and longitudinal wire trussropes D, operated by means of sliding levers V V through the truss-rods E E, or a ratchet around the rod E, working in connection with pawls and levers, as a means of trussing up the elliptic section A A and B B, so as to bear a greater or less weight, as desired.

3. The construction of the upper half-elliptic section, AA, 850., in two parts, so that each half of the bed may be trussed up separately and act independently of each other under the weight or pressure 0t use.

4. The transverse bars K K and the series of coiled springs L L, 860., between them, as a support for the longitudinal truss-ropes D I), to prevent the upper elliptic slats, A A, from being pressed below the line of a plane surface.

5. The folding truss or support, consisting of the legs M M and M M, joint-plates S S, tierails N N, and jointed and pivoted braces P P, so constructed as to be easily attached to the lower section of the elliptics B B by hooks X X and convert the device into a cot-bed, all substantially as described and specified.
